最近考虑换粮,于是到处寻找各种资料,结识了猫小闹创始人阿希,于是聊起一些猫粮制作工艺和营养配方的问题;在我的印象中,Ω-6 有一定促炎症作用,而Ω-3 有一定抑制炎症作用,两者互相平衡,当Ω-6:Ω-3 比例过高有一定负面作用;然鹅阿希给出了否定的答案;
这哪得了;:#tieba-insidious: 以我这么傲娇的性格当然会把问题刨干净;这直接激发了我强烈的抗争到底的兴趣,以前只是印象中,现在我绝对要翻论文;
找到了一篇营养学进展杂志刊登的论文,叫The role of dietary omega-3 and omega-6 essential fatty acids in the nutrition of dogs and cats: A review,它是这么说的:
EPA is mainly a precursor ofeicosanoids. When the diet is richin omega-6 and poor in omega-3fatty acids, eicosanoids are mainlyproduced from AA, but when ani-mals ingest enough omega-3 fattyacids, EPA and DHA partially re-place the omega-6 fatty acids (es-pecially AA) in cell membranes.When the cell is injured, EPA andAA are released from the mem-brane by a phospholipase andmetabolised to eicosanoids by twomain enzymatic systems, ciclooxi-genase and lipoxygenase. The metabolic pathways for the produc-tion of eicosanoids from AA and EPA are shown in figure 2.
Eicosanoids that are derived from AA are pro-inflammatory and pro-aggregatory, and act as potent me-diators of inflammation in type Ihypersensitivity reactions. Eicosa-noids from EPA are less inflamma-tory, vasodilatory, anti-aggregatory,and prevent cardiac arrhythmia (6).These actions resist those producedby the eicosanoids from AA. Themain actions of EPA and AA aresummarized in table 1.
关于 DGLA 的描述,它是Ω-6 的衍生物,有强烈促炎作用;
Dihomo-γ-linolenic acid (DGLA,C20:3 n-6) is produced throughelongation from γ-linolenic acid(GLA, C18:3 n-6). The eicosa-noids (group 1 prostaglandins andgroup 3 leukotrienes) that derivefrom DGLA suppress the synthesisof tumor necrosis factor-a which isa strong proinflammatory cytokine.
当然,所谓的 AA、EPA、DHA 代谢于哪一类脂肪酸家族前文也有详细提及,n-3 就是Ω-3 就是ω-3,不同写法而已;以及,猫无法消化 LA 和 LNA 的原因;
The omega-3 and omega-6 families consist of several fatty acids defatty acids that are available to these enzymes directly affect the quantity and proportions of arachi-donic acid (AA, C20:4 n-6), eicos-apentaenoic (EPA, C20:5 n-3) and docosahexaenoic acid (DHA,C22:6 n-3) that are formed.Like other obligate carnivores, cats show only little d-6 desaturase activity and require foods of animal origin as a source of AA, EPA and DHA (3). Conversely, dogs are able to convert LA and LNA to the long-chain PUFA by desaturase and elongase systems (4, 5).
以及给出了 Table 1 清楚地写明了 AA 和 EPA 代谢物的作用,并且应该很清楚的写明 AA 的 inflammation 都是上升箭头,EPA 的 inflammation 都是下降箭头;
关于 DHA 的部分,原文没有提及到关于炎症的任何信息;这篇论文好是好,就是没提及任何的实验方法,全是定性结论 + 引用,毕竟标题叫 A review;
由于学艺不精,这些很少接触的专业词汇甚是晦涩难懂,只能是一边靠翻译一边看原文;要么是我翻译有问题,要么是我理解有问题,要么就是阿希回答有问题,要么《Progress in Nutrition》期刊也是伪科普;人家是高端猫粮品牌创始人,我没办法随随便便反驳,不过我觉得阿希有机会是出于品牌口碑和销量的目的这么说;但@SuClar 应该有办法回答;:#tieba-insidious:
